'Vifliis invention relates to the construction ont springs sdapjted for seats and seat-books, and its e :fiest is toprovide o enslnonspring lil.- lo sliall. los soit and iesilient, and 'Whereq .tree ed This invention consists in combination Witli a frame., of lieiioal springs mounted .thereon in parallel rows, of transverse springs, minimising thin Vbands oi resilient metal5 conneeting to'tlie frame at, one end and extending over the tops of the helical spiings, s. ,longitudinal strip o resilient eonneeting the free ends of the tansverse spinge, and means attached to,.said tndinai 'bend and to the frame for' the i t g the movement of the en s oi? said tiansv e springs.

Fig. 3 is e similar eleien of a slightly niodied construction. is 'an end elevation of the top of an oilied .tornooi transverse sprint?. s plan el" the strip which connects ee ends et' the transverse springs. D. milan ieiei'enoe characters refer to like s tiiivonglimit the seveiai views. intenso-toile bnildefs have been endeav to psodnoe cushion springs :for loeii'i "seeks which shall give maximum t to'p'assengers when the vehicle is ti'ai sling at high speed over rough roads. it 4been found the thiol; pad et led liaiiy hitherto almost universally ein- J ed te npliolstei" the seats and laaeks7 was iisly satisacto y, as it did not yield Vy when i seing-ers were subjected iolts and jars oeoause of the nnevenness ot ti e ioadw y over which the vehicle was lt also found that by 'using was attained. .in many eases it is desirable that the cushion-springs sliallextend the.

entire height of. the backs, in which case the .cushion on the seat extends reaifwardly against' theleushion for the back. in seine eases, however, this is not so desirable as to have 'the seat-cushion extend the full Width of the seat and to lieve the loaoleoushion entend down only to the seat-cushion. The construction shown in the drawings is par'- 'ticularly adapted' for this latteeform of euslv ions. The resilient portion of this con struction. when used for seatdiaoksyis mounted on a iframe preievably composed o'liin'i zontal laars l, 2, 3 and 4, which areconnected. by means ofI `upright bars 5.. Helical springs 6 are` mounted on this trame 'and preferably connected immediately to the vertical bars 5, and arranged in parallel iows as shown in Fig. l. Springs 7, inthe form of thin strips of spring-metal, saches steel o1' brass, connect 'at one end to the -upper bar l andv then extend upward,. forward fand downward across the outer ends of the helical springs 6, connecting theeto in any desired manner. Extendingalong and oonmeeting to the lower ends of' these flat, trans verse springs T, is a thin` resilient cross.- bai 8 having rentiant bends 9, as shown 1n Fig. 5. so that the movement of one spring '7 will loe transmitted in part to the adjacent springs on eaeli side. Whenever the pad 10, which entends over this cushion construetion., is depressed at any one place, the lower ends of the springs 7 will yield and the bei' 8 will bend. In order "to vprevent this bei' 'from dra-Wing the-ends the springs 7 laterally, the bai" 8 is made en ansible by means oi' 'the i'entrant'bends 9. y

vliefeisf-ing to Fig. 2, it -`will loe noticed that the Weight of the psd l() and` of the springs, is liable to cause the helical springs 6 and the swings 7 to sag-. ,ln orderto prevent this, the supporting inemloois l2, Whioli formed from stili spring-metal strips, Connect to the ontei', ends of the loai4 S, and after ourving, at the upper end,' connect to the outer ends of the longitudinal oars 1 and 2. ii* desired. additional spring members 13 may be placed in the bendl oi the supporting member l2 to stiilen the saine. As shown in Fig. te@ seateusliion l5 may -be slipped 'di the lowei` edge et" the spring eenen-lieti n :inst described.

lllne is desired te embody this invention in a seat spring, no change -need be made in the details, as all parts may be the same as those just described. If the drawing be turned to the right through an angle of about eighty degrees, Fig. 2 will represent a seat-cushion construction, and. the back cushion will be indicated in dotted lines by the part 15 andwill extend down to the seat 17. Any desired means may be employed to secure the frame to the back 16, and the distance from the bar -8 to the seat- 17 will depend upon the general construction and design of the vehicle.

fInstead of the springs 7 shown in Fig. 2, it" may be desirable to use the fiat strips 18, formed with rentrant bends 19, as shown in Fig. 3'. This second construction is especially adapted for limousines where there is, no possibility of the upper curved portions of the springs 7 swinging back beyond the ffront line of the seat-back 16, as the seat-back 20 of the limousine usually extends upwardly beyond the top of the cushion. Where the transverse springs are -ormed with rentrant bends as shown in Fig. 3, the upper portion will contract under pressure. Another method offorming these rentr'ant bends is shown in Fig. 4, where the dat springs 21 are formed with sharp bends 22; These may be desirable where the construction shown in Fig. 3 might be objectionable, owing to the clicking sounds resulting from theedges 24, at the openings formed by the n bends, contacting when unusual pressure is exerted on the springs. To prevent the pad y 10 from saggingdown between the springs 7 28 may exten or l18, small coil springs 26 may be employed to connect the upper bends of thetransverse springs 7. In order to hold the'springs 7 parallel to each other,v clips 27 may be secured to them, between which clips the wires isot limitedin the number and size of the 'heliV ai springs 6, nor to the designs of the l upper `portions of the transverse springs 7 butresidesin the 'lower portions of these nectionk with' the upper-edge of the f ran1e,ja-\

springs, the connecting member 8, and the 0 up'porting members 12 therefor. The frame 5 ormed by the bars 1 tol5 inclusive, may be 5`- ttedand theylparts securedto the back -1'6 'rf any other desirablesupport.

.,ti'on' ofafs'upporting frame, a series of he1icalspringsmounte 4thereon inlongitudinal rows, a" s`eries of flat; springs extending {transaersely-'across the tops' of the-helical 'springs Iand curving to their points of conmembers connecting to the ends of said bar and t'o the upper part of said frame.

2. In a spring construction, the combination of a supporting frame, a series of helical vsprings mounted thereon, substantially parallel flat springs secured to the upper part of the frame and extending forward and then downward across the outer ends of the helical springs and connecting thereto, means connecting the Hat springs between their connection with the frame and the upper helical springs. a resilient bar connecting the lower ends of the flat springs 1and having rentrant portions between said at springs, and strips of spring-metal connecting to the ends of said bar and extending upwardly, and havingtheiru per portions bent substantially U-shaped an theirends secured to the upper part of the frame so asto forma resilient support for said bar and springs.

3. In a spring construction, the combination of a supporting frame, a series of heli-l right springs from sagging an undesirable amount under the weight of y the upholstering.

4. In a spring construction, the combination of a rigid frame comprising horizontal and upright bars secured together, helical springs mounted on said frame, substantially flat springs secured to the upper part ofthe frame and forming arches to support upholstering andthen extending vdownward across the outer ends of the helical springs` andconnected thereto, a resilient bar connecting the lower ends ofthe dat springs, and a pair of supporting members extending from said bar to therigid frame to prevent 'the'sprin'g construction from sagging under the weight of the upholstering. if In 'testimony lwhereof I f havelisignedv this specification in thepresence lof. two subscribing witnesses.
